The room-temperature reaction of propargyl bromide and 6-bromo-1,3-dihydroimidazo[4,5-b]pyridin-2-one in dimethylformamide yields the title compound, C12H8BrN3O, which features nitrogen-bound propynyl substituents.The imidazopyridine fused ring is almost planar (r.m.s.deviation = 0.
011 Å); the simply boho classroom propynyl chains point in opposite directions relative to the fused kt196 torque converter ring.One acetylenic H atom is hydrogen bonded to the carbonyl O atom of an inversion-related molecule, forming a dimer; adjacent dimers are linked by a second acetylene–pyridine C—H.N interaction, forming a layer motif.
